Re: Sar not working...!!

Have you tried reading the man page?

"In the second form, with no sampling interval specified, sar extracts data from a previously recorded file, either the one specified by -f option or, by default, the standard system ctivity daily data file /var/adm/sa/sadd for the current day dd."

it's looking for the sa05 file because today is 05 March. You would create the file by running sar with the -o option:

"If the -o option is specified, it saves the samples in file in binary format."

The man pages are your friend!
